Fronc'rtlie 'benk or receiver' e mein air supply lpe llesds vdown to the different mine. levels, but one olvvhich is deemed necessary here to loesliwn.

' The mineV preferably worked in' two di,

retions. from the mein or hoisting slieft lll.

Inorder to accomplish this purpose drifts or headings ,l5 @remade in both. directions from points on the shaft 14. After these drifts or needings l5 lieve been driven the essere@ l@ er@ extending laterally therefrom. From the crosseuts 16 the drifts 15 are continued in their original direction and otherdrifts 17 and 18 are also made from the cross-cuts parallel to the heading 15.v These three are united at various points by cross-cuts 19, and the headings'l are connected as shovn at 20. At a suitable point on the connecting heading 2O is located the u -take shaft 21. Rooms 22 extend'lateraly from the drifts 15 and 18 being arranged in pairs. Each pair of rooms is connected by a crosscut 23. In each of the rooms 22 is formed a safety chamber 24, the referable floor dimensions of vhich are a out 6 by 10 ft. In the preferred arrangement one of the rooms 22 of each pair lies op osite one of the cross-cuts 19 between the eadings 15,

- 17 and 18, vhile the oth'er lies intermediate each pair of crosscuts 19. Do0rs25 are provided on one of each pair of the rooms 22 and an over-cast 26 extends from the room closed by the'door to connect vith one of the cross-cuts 19 opposite that door. All of the cross-cuts except the one nearest the end of the headings are provided with suit- ,able sto pings 27, and the cross-cuts 16 are 'provide' with doors 28. These doors are arranged to be' normally closed except during the assage of a mine ear or person.

y. Above t e cross-eut 16 there is provided suitable over-'casts not here shown as the constructionis that usual in such cases. At any point which may be found c'onvenient there is provided a Ventilating fan 28', arranged tewerk on the lenum system.

While the fan is here s ovm arranged to work on the plenum system, yet it is obvious that the same may be arranged in the up.

take shaft to Work on `the vacuum system. Now let it be considered that all ofthe doors arel closed and the fan in operation. A

L current of air will be blovs'n along the rst part ofthe headings 15 until it arrives at the cross-cut 16. At this point the current will pass over the cross-cut 16 through the overcast at that point and pass down the heading 18, va part of the air continuing along the extension of the headin 15. As the air passes along it v ill enter each ofthe open rooms and pass through the various cross cuts 23 and Into the closed rooms; from the closed rooms it vill pass through the over-casts 26 intothe heading' 17, from there it will pass into the heading 2O and up the up-take shaft '21. By this it 1s seen that each of the rooms is provided with a supply of pure and fresh air vshile the exhaust airvithall of the noxious gases is carried loff through a closed heading vhich is practically unused. The workmen are thus provided with fresh air at all parts of the mine and/ not as is usual in most ca es, v here the Workmen nearest the shaft secure a supply of frelh air vi hile these further avr y are forced to Ireathe the accumulated gases from the inlet side of thebrattice that is ordinarily used.

To return new'to the compressed air i supply. The pipe 13, as has been heretofore described, extends downward to the various langled to extend into the chamber 24 in each of the rooms 22.

Referring new' to Fig. 4, each of the chambers 24 is provided with a door 33 and the ipe leadin into that chamber is provide with a va ve as indicated at 34. On each of the doors 33 is a lever 35fso arranged as to actuate the valve 34. This lever is so connected to the valve that when the door is opened the valve will be closed, and when the door is shut the valve will bev opened. In each of the chambers 24 the door 33 is provided With a relief valve 36. This"` relief valve is of the adjustable type and is provided interiorly of the door with an adjusting handle 37. Under ordinary circumn stances the relief valve will be set at a little above the pressure of the main Ventilating system previously described, so that i the pressure in the' chamber will not exceed that to which the Workman has been accustomed. Under some circumstances, however, itmay vbe deemed advisable to increase the pressure in the chambers 24. If that be the case, the person in the chamber can readily adjust the valve 36 by means,y of the handle 37 so that the pressure may/ be increased to any requiredv degree. These circumstances can best be understood by assuming a specific ease. Let, it be' assumed that the mine is Hooded by'water. The Workmen retreat to the chambers 24 and close the doors 33. if the rooms in which they are Working become flooded, by inereasingthe pressure, by adustin the valve 37, the room itself ma be ept ee from Water as the compresse( air coming ,in through' the pipe 32, when the pressure in the room is properly adjusted,

prevents the Water from entering. ,f

It will now be obvious that thereY as been? doors of the chambers 24 it is to be under-l ,30
